Abstract
Providing electric power distribution for fracturing operations comprising receiving, at a transport, electric power from a mobile source of electricity at a first voltage level and supplying, from the transport, the electric power to a fracturing pump transport at the first voltage level using only a first, single cable connection. The first voltage level falls within a range of 1,000 V to 35 kilovolts. The transport also supplies electric power to a second transport at the first voltage level using only a second, single cable connection.
Claims23
An electric fracturing system for use with at least one power generation source providing source electric power, the system comprising:
- a switch gear transport electrically connected to the at least one power generation source and configured to receive the source electric power at a first medium voltage level;
- a first electrical cable connected to the switch gear transport that supplies first electric power at the first medium voltage level from the switch gear transport;
- and
- a first fracturing pump transport comprising:
- at least one first transformer, at least one drive, at least one electric prime mover, and at least one pump, each being disposed on the first fracturing pump transport,
- wherein the at least one first transformer is electrically connected to the switch gear transport via only the first electrical cable, wherein the at least one first transformer is further electrically connected to the at least one electric prime mover and to the at least one drive,
- wherein the at least one first transformer is configured to step down the first electric power received at the first medium voltage level to a first lower medium voltage level that powers the at least one electric prime mover,
- wherein each of the at least one drive and the at least one pump is coupled to the at least one electric prime mover, and
- wherein the at least one first transformer is further configured to step down the first electric power received at the first medium voltage level to a first low voltage level that is lower than the first lower medium voltage level and that powers the at least one drive.
A fracturing transport for fracturing operations, the fracturing transport used with a switch gear transport providing electric power and comprising:
- a single transport frame;
- at least one electric prime mover mounted on the single transport frame;
- a drive mounted on the single transport frame and coupled to the at least one electric prime mover;
- a plurality of pumps coupled to the electric prime mover and mounted on the single transport frame;
- and
- at least one transformer coupled through the drive to the electric prime mover and mounted on the single transport frame, wherein the transformer is configured to:
- receive electric power at a first medium voltage level from the switch gear transport via a single cable assembly;
- step down the electric power at the first medium voltage level to a lower medium voltage level, and supply the electric power at the lower medium voltage level through the drive to the electric prime mover to drive the pumps;
- and
- step down the electric power at the first medium voltage level to a low voltage level, and supply the electric power at the low voltage level to the drive,
- wherein the fracturing transport is not connected to any other cable assemblies that supply electric power at the first medium voltage level and other voltage levels.
A method for electric power distribution for fracturing operations, the method comprising:
- receiving, at a switch gear transport, source electric power from at least one mobile source of electricity at a first medium voltage level;
- supplying, from the switch gear transport, first electric power at the first medium voltage level using only a first cable connection;
- receiving, at a fracturing pump transport, the first electric power at the first medium voltage level supplied directly using the first cable connection;
- stepping down, with at least one first transformer disposed on the fracturing pump transport, the first medium voltage level to both a lower medium voltage level and a low voltage level;
- powering an electric prime mover disposed on the fracturing pump transport with the lower medium voltage level;
- powering a drive disposed on the fracturing pump transport with the low voltage level;
- and
- controlling output of the powered electric prime mover with the powered drive.
